docker-vagrant-libvirt

A docker container for vagrant-libvirt. Basically, I put these instructions into a docker container (except I used the embedded vagrant ruby instead of rvm).

Docker Hub Repository

https://registry.hub.docker.com/u/twiest/docker-vagrant-libvirt/

Build

docker build -t vagrant_libvirt:latest .

Run From Docker Hub (recommended)

docker run --rm --privileged=true --net=host -v /var/lib/libvirt:/var/lib/libvirt -v /var/run/libvirt:/var/run/libvirt -v /var/lib/ctr-vagrant-libvirt:/persistent-data -ti twiest/docker-vagrant-libvirt

Run From Manual Build

docker run --rm --privileged=true --net=host -v /var/lib/libvirt:/var/lib/libvirt -v /var/run/libvirt:/var/run/libvirt -v /var/lib/ctr-vagrant-libvirt:/persistent-data -ti vagrant_libvirt

Notes

• Use the accompanying enter-container.sh script from outside of the running container to be able to have multiple terminals into the same container.

• The docker image is fairly big (docker says it has a "virtual size" of 1.5G)

• This container has to run with --net=host so that vagrant can talk to the launched VMs

• This container has to run privileged so that it can communicate with the libvirt socket

• Libvirt must still be setup on the host machine. See the section "KVM/QEMU installation" from here: https://ttboj.wordpress.com/2014/05/13/vagrant-on-fedora-with-libvirt-reprise/

• /var/lib/libvirt and /var/run/libvirt are both mounted into the docker container so that it can interact with libvirt

• libvirt commands work inside the docker container. For example: virsh list --all

• This container uses /persistent-data to store vagrant box images, and other persistent data. The command above uses /var/lib/ctr-vagrant-libvirt as the persistent directory, but any directory can be used.

• Only tested on Fedora 20 x86_64, but may work elsewhere

• Inside the container, the current directory is the oh-my-vagrant check out, so 'vs' and other aliased vagrant commands work without having to change directories.

• You'll still need to import vagrant boxes with a command like this: vagrant box add http://file.example.com/vagrant/rhel-7.0/rhel-7.0.box --name rhel-7.0
